RESUMEN

To date, few reports have evaluated the pneumococcal vaccination status in cirrhotic patients. No data are available for European countries. We have explored this topic and the potential independent predictors motivating lack of vaccination in Italy. Between January 1st and June 30th 2022, 1419 cirrhotic patients of any etiology were consecutively enrolled in an observational, prospective study at 8 referral centers in Italy. Adjusted odds ratios (ORs) for the association with lack of vaccination were evaluated by multiple logistic regression analysis. Overall vaccine coverage was 17.9% (8.9% in patients < 65 years of age and 27.1% in those aged ≥ 65 years; p < 0.001). Among the 1165 unvaccinated patients, 1068 (91.7%) reported lack of information regarding vaccination as the reason for not having undergone vaccination. Independent predictors associated with lack of vaccination were age < 65 years (OR 3.39, CI 95% 2.41-4.76) and a higher number of schooling years (OR 2.14, CI 95% 1.58-2.91); alcoholic etiology resulted only marginally associated (OR 1.91, CI 95% 1.03-3.52). These findings establish evidence on how pneumococcal vaccination status in Italy is largely suboptimal among cirrhotic patients. These results raise concern, considering the severe outcomes of pneumococcal infection in patients with chronic liver diseases.

RESUMEN

We have evaluated flu vaccine coverage and variables associated with the lack of vaccination in cirrhotic subjects with particular attention to the cirrhosis etiology. Cirrhotic subjects consecutively referring to eight Italian centers were prospectively enrolled for a 6-month period in 2019. Subjects were asked if they had received a flu vaccine in the last 12 months. Multiple logistic regression analysis was performed to identify independent predictors of lack of vaccination. A total of 818 cases were recruited. The overall vaccine coverage was 39.6% (26.9% in those younger than 65 years and 51.9% in those older than 64 years; p < 0.001). Age < 65 years (odds ratio [OR] = 2.38; 95% confidence interval [CI] = 1.68-3.36), alcoholic etiology (OR = 2.40; 95% CI = 1.49-3.85), birth abroad (OR = 2.7; 95% CI = 1.10-6.61), and residence in South/Sardinia island (OR = 1.66; 95% CI = 1.14-2.42) all resulted independent predictors of the likelihood of lack of vaccination. The lack of information regarding the vaccine as the reason for no vaccination was reported by 71.4% of foreigners and by 34.7% of natives (p < 0.001). In conclusion, much work still should be done to improve coverage among groups at higher risk of lack of vaccination identified in this survey. The ongoing SARS-CoV-2 pandemic may represent one more alert for improving seasonal flu vaccine coverage to avoid further stress to the National Health System.

RESUMEN

The study was undertaken in order to provide a snapshot from real clinical practice of virological presentation and outcome of patients developing immunosuppression-driven HBV reactivation. Seventy patients with HBV reactivation were included (66.2% treated with rituximab, 10% with corticosteroids and 23.8% with other immunosuppressive drugs). Following HBV reactivation, patients received anti-HBV treatment for a median (IQR) follow-up of 31(13-47) months. At baseline-screening, 72.9% of patients were HBsAg-negative and 27.1% HBsAg-positive. About 71.4% had a diagnosis of biochemical reactivation [median (IQR) HBV DNA and ALT: 6.9 (5.4-7.8) log IU/mL and 359 (102-775) U/L]. Moreover, 10% of patients died from hepatic failure. Antiviral prophylaxis was documented in 57.9% and 15.7% of HBsAg-positive and HBsAg-negative patients at baseline-screening (median [IQR] prophylaxis duration: 24[15-33] and 25[17-36] months, respectively). Notably, HBV reactivation occurred 2-24 months after completing the recommended course of anti-HBV prophylaxis in 35.3% of patients. By analysing treatment outcome, the cumulative probability of ALT normalization and of virological suppression was 97% and 69%, respectively. Nevertheless, in patients negative to HBsAg at baseline-screening, only 27% returned to HBsAg-negative status during prolonged follow-up, suggesting the establishment of chronic infection. In conclusion, most patients received a diagnosis of HBV reactivation accompanied by high ALT and 10% died for hepatic failure, supporting the importance of strict monitoring for an early HBV reactivation diagnosis. Furthermore, HBV reactivation correlates with high risk of HBV chronicity in patients negative for HBsAg at baseline-screening, converting a silent into a chronic infection, requiring long-term antiviral treatment. Finally, a relevant proportion of patients experienced HBV reactivation after completing the recommended course of anti-HBV prophylaxis, suggesting the need to reconsider proper duration of prophylaxis particularly in profound immunosuppression.

RESUMEN

Several staging systems for hepatocellular carcinoma (HCC) have been developed. The Barcelona Clinic Liver Cancer staging system is considered the best in predicting survival, although limitations have emerged. Recently, the Italian Liver Cancer (ITA.LI.CA) prognostic system, integrating ITA.LI.CA tumor staging (stages 0, A, B1-3, C) with the Child-Turcotte-Pugh score, Eastern Cooperative Oncology Group performance status, and alpha-fetoprotein with a strong ability to predict survival, was proposed. The aim of our study was to provide an external validation of the ITA.LI.CA system in an independent real-life occidental cohort of HCCs. From September 2008 to April 2016, 1,508 patients with cirrhosis and incident HCC were consecutively enrolled in 27 Italian institutions. Clinical, tumor, and treatment-related variables were collected, and patients were stratified according to scores of the Barcelona Clinic Liver Cancer system, ITA.LI.CA prognostic system, Hong Kong Liver Cancer system, Cancer of the Liver Italian Program, Japanese Integrated System, and model to estimate survival in ambulatory patients with hepatocellular carcinoma. Harrell's C-index, Akaike information criterion, and likelihood-ratio test were used to compare the predictive ability of the different systems. A subgroup analysis for treatment category (curative versus palliative) was performed. Median follow-up was 44 months (interquartile range, 23-63 months), and median overall survival was 34 months (interquartile range, 13-82 months). Median age was 71 years, and patients were mainly male individuals and hepatitis C virus carriers. According to ITA.LI.CA tumor staging, 246 patients were in stage 0, 472 were in stage A, 657 were in stages B1/3, and 133 were in stage C. The ITA.LI.CA prognostic system showed the best discriminatory ability (C-index = 0.77) and monotonicity of gradients compared to other systems, and its superiority was also confirmed after stratification for treatment strategy. CONCLUSION: This is the first study that independently validated the ITA.LI.CA prognostic system in a large cohort of Western patients with incident HCCs. The ITA.LI.CA system performed better than other multidimensional prognostic systems, even after stratification by curative or palliative treatment. This new system appears to be particularly useful for predicting individual HCC prognosis in clinical practice. (Hepatology 2018;67:2215-2225).

RESUMEN

Prognostic assessment of patients with hepatocellular carcinoma (HCC) at the time of diagnosis remains controversial and becomes even more complex at the time of restaging when new variables need to be considered. The aim of the current study was to evaluate the prognostic utility of restaging patients before proceeding with additional therapies for HCC. Two independent Italian prospective databases were used to identify 1,196 (training cohort) and 648 (validation cohort) consecutive patients with HCC treated over the same study period (2008-2015) who had complete restaging before decisions about additional therapies. The performance of the Italian Liver Cancer (ITA.LI.CA) prognostic score at restaging was compared with that of the Barcelona Clinic Liver Cancer, Hong Kong Liver Cancer, and Cancer of the Liver Italian Program systems. A multivariable Cox survival analysis was performed to identify baseline, restaging, or dynamic variables that were able to improve the predictive performance of the prognostic systems. At restaging, 35.3% of patients maintained stable disease; most patients were either down-staged by treatment (27.2%) or had disease progression (37.5%). The ITA.LI.CA scoring system at restaging demonstrated the best prognostic performance in both the training and validation cohorts (c-index 0.707 and 0.722, respectively) among all systems examined. On multivariable analysis, several variables improved the prognostic ability of the ITA.LI.CA score at restaging, including progressive disease after the first treatment, Model for End-Stage Liver Disease at restaging, and choice of nonsurgical treatment as additional therapy. A new ITA.LI.CA restaging model was created that demonstrated high discriminative power in both the training and validation cohorts (c-index 0.753 and 0.745, respectively). CONCLUSION: Although the ITA.LI.CA score demonstrated the best prognostic performance at restaging, other variables should be considered to improve the prognostic assessment of patients at the time of deciding additional therapies for HCC.

RESUMEN

AIMS: This multicentre cohort study evaluated the role of ageing on clinical characteristics, treatment allocation and outcome of new hepatocellular carcinomas (HCCs), in clinical practice. MATERIAL & METHODS: From September 2008, 541 patients >70 years old (elderly group), and 527 ≤70 years old (non-elderly group) with newly diagnosed HCC were consecutively enrolled in 30 Italian centres. Differences in clinical characteristics and treatment allocation between groups were described by a multivariable logistic regression model measuring the inverse probability weight to meet the elderly group. Survival differences were measured by unadjusted and adjusted (by inverse probability weight) survival analysis. RESULTS: Elderly patients were mainly females, hepatitis C virus infected and with better conserved liver function (P<.001). At presentation, HCC median size was similar in both groups while, in youngers, HCC was more frequently multinodular (P=.001), and associated with neoplastic thrombosis (P=.009). Adjusted survival analysis showed that age did not predict short-mid-term survival (within 24 months), while it was a significant independent predictor of long-term survival. Moreover, age had a significant long-term survival impact mainly on early HCC stages (Barcelona Clinic for Liver Cancer [BCLC] 0-A), its impact on BCLC B stage was lower, while it was negligible for advanced-terminal stages. CONCLUSIONS: Age per se does not impact on short-mid-term prognosis (≤24 months) of HCC patients, and should not represent a limitation to its management.

RESUMEN

BACKGROUND & AIMS: The proportion of HCV-infected patients over age 65 years in Western countries is increasing. This growth and the advent of new antiviral therapy bring into the question the real-world efficacy and safety of the combination of sofosbuvir (SOF) and simeprevir (SMV) plus a flat dose of 800 mg/d ribavirin (RBV) in elderly patients with cirrhosis compared to younger patients. METHODS: Retrospective observational multicentre real-life investigation study of SOF/SMV/RBV for a duration of 12 weeks in HCV genotype 1-infected patients with cirrhosis. RESULTS: Of the 270 patients enrolled in this study, with compensated cirrhosis, 133 (49.2%) were ≥65 years of age. Sustained virological response at 12 weeks (SVR12) was achieved by 94.2% (129/137) of those aged <65 years and 97.7% (130/133) of those ≥65 years. Diabetes was the most common comorbidity in patients ≥65 years compared to younger patients (26.3% vs 12.4% P<.003). The most common adverse event (AE) in elderly patients was a grade 2 anaemia (35.3% vs 19.9% P<.004). CONCLUSIONS: Sofosbuvir/simeprevir plus a daily flat dose of RBV 800 mg for 12 weeks was highly effective and safe in genotype 1 elderly patients with compensated cirrhosis.

RESUMEN

 Background. Sarcopenia is a complication and independent risk factor for mortality in patients with liver cirrhosis. AIM: To assess the prevalence and influence of sarcopenia on overall survival in a cohort of cirrhotic patients with hepatocellular carcinoma managed in a tertiary center. MATERIAL AND METHODS: Abdominal computed tomography of 92 consecutive hepatocellular carcinoma cirrhotic patients, enrolled and followed from 2004 to 2014, were retrospectively studied with a software analyzing the cross-sectional areas of muscles at third lumbar vertebra level. Data was normalized for height, skeletal muscle index (SMI) calculated and presence of Sarcopenia measured. Sarcopenia was defined by SMI ≤ 41 cm2/m2 for women and ≤ 53 cm2/m2 for men with body mass index (BMI) ≥ 25, and ≤ 43 cm2/m2 for men and women with BMI < 25, respectively. RESULTS: Median age at diagnosis was 71.9 years (30.7-86.4) and BMI 24.7 (17.5-36.7), comparable in women 23.1, (17.5-36.7) and men 24.7 (18.4-36.7). A class of CHILD score and BCLC A prevailed (55.4% and 41.3%, respectively); metastatic disease was found in 12% of cases. Sarcopenia was present in 40.2% of cases, mostly in females (62.9%; p = 0.005). Mean overall survival was reduced in sarcopenic patients, 66 (95% CI 47 to 84) vs. 123 (95% CI 98 to 150) weeks (p = 0.001). At multivariate analysis, sarcopenia was a predictor of reduced overall survival, independent of age (p = 0.0027). CONCLUSIONS: This retrospective study shows high prevalence of sarcopenia among cirrhotic patients with hepatocellular carcinoma. Presence of sarcopenia was identified as independent predictor of reduced overall survival. As easily measurable by CT, sarcopenia should be determined for prognostic purposes in this patient population.

RESUMEN

UNLABELLED: Hepatitis B virus (HBV) reactivation during immunosuppression can lead to severe acute hepatitis, fulminant liver failure, and death. Here, we investigated hepatitis B surface antigen (HBsAg) genetic features underlying this phenomenon by analyzing 93 patients: 29 developing HBV reactivation and 64 consecutive patients with chronic HBV infection (as control). HBsAg genetic diversity was analyzed by population-based and ultradeep sequencing (UDS). Before HBV reactivation, 51.7% of patients were isolated hepatitis B core antibody (anti-HBc) positive, 31.0% inactive carriers, 6.9% anti-HBc/anti-HBs (hepatitis B surface antibody) positive, 6.9% isolated anti-HBs positive, and 3.4% had an overt HBV infection. Of HBV-reactivated patients, 51.7% were treated with rituximab, 34.5% with different chemotherapeutics, and 13.8% with corticosteroids only for inflammatory diseases. In total, 75.9% of HBV-reactivated patients (vs. 3.1% of control patients; P<0.001) carried HBsAg mutations localized in immune-active HBsAg regions. Of the 13 HBsAg mutations found in these patients, 8 of 13 (M103I-L109I-T118K-P120A-Y134H-S143L-D144E-S171F) reside in a major hydrophilic loop (target of neutralizing antibodies [Abs]); some of them are already known to hamper HBsAg recognition by humoral response. The remaining five (C48G-V96A-L175S-G185E-V190A) are localized in class I/II-restricted T-cell epitopes, suggesting a role in HBV escape from T-cell-mediated responses. By UDS, these mutations occurred in HBV-reactivated patients with a median intrapatient prevalence of 73.3% (range, 27.6%-100%) supporting their fixation in the viral population as a predominant species. In control patients carrying such mutations, their median intrapatient prevalence was 4.6% (range, 2.5%-11.3%; P<0.001). Finally, additional N-linked glycosylation (NLG) sites within the major hydrophilic loop were found in 24.1% of HBV-reactivated patients (vs. 0% of chronic patients; P<0.001); 5 of 7 patients carrying these sites remained HBsAg negative despite HBV reactivation. NLG can mask immunogenic epitopes, abrogating HBsAg recognition by Abs. CONCLUSION: HBV reactivation occurs in a wide variety of clinical settings requiring immune-suppressive therapy, and correlates with HBsAg mutations endowed with enhanced capability to evade immune response. This highlights the need for careful patient monitoring in all immunosuppressive settings at reactivation risk and of establishing a prompt therapy to prevent HBV-related clinical complications.

RESUMEN

BACKGROUND: Some beneficial effects of probiotics may be due to secreted probiotic-derived factors, identified as "postbiotic" mediators. The aim of this study was to evaluate whether supernatants harvested from Lactobacillus rhamnosus GG (LGG) cultures (ATCC53103 strain) protect colonic human smooth muscle cells (HSMCs) from lipopolysaccharide (LPS)-induced myogenic damage. MATERIALS AND METHODS: LGG was grown in de Man, Rogosa, Share medium at 37°C and samples were collected in middle and late exponential, stationary, and overnight phases. Supernatants were recovered by centrifugation, filtered, and stored at -20°C. The primary HSMCs culture was exposed for 24 hours to purified LPS of a pathogen strain of Escherichia coli (O111:B4) (1 µg/mL) with and without supernatants. Postbiotic effects were evaluated on the basis of HSMCs morphofunctional alterations and interleukin-6 (IL-6) production. Data are expressed as mean±SE (P<0.05 significant). RESULTS: LPS induced persistent, significant, 20.5%±0.7% cell shortening and 34.5%±2.2% decrease in acetylcholine-induced contraction of human HSMCs. These morphofunctional alterations were paralleled to a 365.65%±203.13% increase in IL-6 production. All these effects were dose-dependently reduced by LGG supernatants. Supernatants of the middle exponential phase already partially restored LPS-induced cell shortening by 57.34%±12.7% and IL-6 increase by 145.8%±4.3% but had no effect on LPS-induced inhibition of contraction. Maximal protective effects were obtained with supernatants of the late stationary phase with LPS-induced cell shortening restored by 84.1%±4.7%, inhibition of contraction by 85.5%±6.4%, and IL-6 basal production by 92.7%±1.2%. CONCLUSIONS: LGG-derived products are able to protect human SMCs from LPS-induced myogenic damage. Novel insights have been provided for the possibility that LGG-derived products could reduce the risk of progression to postinfective motor disorders.

RESUMEN

BACKGROUND: Recent data suggest that outcome of hepatocarcinoma is improving. AIMS: In order to explore whether survival is also increasing in clinical practice, we compared two multicenter independent in-field cohorts of cirrhotics with newly diagnosed HCCs. METHODS: Cohort 1 (C1) consisted of 327 patients enrolled between January and December 1998, and cohort 2 (C2) included 826 patients enrolled between September 2008 and November 2012. Patients were stratified according to Child-Pugh score, MELD score, and HCC staged according to TNM, BCLC systems. RESULTS: At baseline, C2 patients were significantly older, with more frequent comorbidities and better liver function. In C2, HCC was more frequently detected under regular ultrasound surveillance (P < 0.001), BCLC early stages were more frequent, and rates of smaller and uni/paucinodular tumors were significantly higher. Treatment of any type was more frequently offered to C2 patients (P < 0.001). Proportion of patients treated by TACE increased, and radiofrequency ablation was the most used ablative treatment. Survival rate was significantly higher in C2 being C1 and C2 survival at 1-3 years 72-25 and 75-44 %, respectively. Child-Pugh score A, BCLC stage A, single nodule, size ≤ 3 cm, belonging to cohort C2 and treatment per se independently predicted survival. CONCLUSIONS: This in-field study showed a trend on improved HCC outcomes over time, which seems to be mainly due to a better presentation thanks to the wider application of surveillance and increased propensity to treat patients. These encouraging data should support further efforts to implement such approach to HCC in everyday clinical practice.

RESUMEN

INTRODUCTION: Sorafenib, an oral multikinase inhibitor, is the only targeted agent approved for the treatment of patients with hepatocellular carcinoma (HCC) after demonstration to increase overall survival compared to placebo in two randomized phase III study. GIDEON (Global Investigation of therapeutic DEcisions in HCC and Of its treatment with sorafeNib) is the largest, global, non-interventional, prospective study of patients with uHCC (n>3200) treated with sorafenib in real-life clinical practice conditions. Here we report the final analysis of safety and efficacy in the Italian cohort of patients. METHODS: Patients with unresectable HCC who are candidates for systemic therapy, and for whom a decision has been made to treat with sorafenib, are eligible for inclusion. Patients demographics disease characteristics and treatment history were recorded at baseline visit. Sorafenib dose, concomitant medications, performance status, liver function, adverse events and efficacy (survival and response rate) were collected throughout the study. RESULTS: In the Italian cohort of the GIDEON study 278 patients were included in 36 centers. The global rate of adverse events was 81%. Drug-related events accounted for 67%, mostly of grade 1 and 2, and only 8% were classified as serious. The most common were diarrhea (24%), fatigue (23%), dermatological (14%), rash/exfoliation (10%), hypertension (9%), hemorrage/bleeding of gastrointestinal tract (6%). Overall survival was 14.4 months and time to progression 6.2 months. Objective responses were observed in 14 patients (5%) with 3 complete responses (1%). Stable diseases of at least 6 weeks were observed in 113 patients (41%) with a 30% of disease control rate. DISCUSSION: The safety profile of sorafenib in terms of rate and type of adverse events is similar to that emerged in the global international GIDEON study as well as in the pivotal registration studies.

RESUMEN

Probiotics are alive nonpathogenic microorganisms present in the gut microbiota that confer benefits to the host for his health. They act through molecular and cellular mechanisms that contrast pathogen bacteria adhesion, enhance innate immunity, decrease pathogen-induced inflammation, and promote intestinal epithelial cell survival, barrier function, and protective responses. Some of these beneficial effects result to be determined by secreted probiotic-derived factors that recently have been identified as "postbiotic" mediators. They have been reported for several probiotic strains but most available literature concerns Lactobacilli. In this review, we focus on the reported actions of several secretory products of different Lactobacillus species highlighting the available mechanistic data. The identification of soluble factors mediating the beneficial effects of probiotics may present an opportunity not only to understand their fine mechanisms of action, but also to develop effective pharmacological strategies that could integrate the action of treatments with live bacteria.

RESUMEN

Hepatitis E virus (HEV) is the most important causative agent of acute hepatitis in developing countries. The disease is usually characterized by a self-limiting, benign course. However, when particular conditions coexist (pregnancy, old age, pre-existing liver disease) it may run an unfavourable course. To date, 4 HEV genotypes have been described. Historically, in the Western world, HEV infection was considered a travel-related disease, however in the last 2 decades a great number of non-travel-related autochthonous cases have been described, more often related to genotype 3 or 4 and in the context of zoonosis. We report the case of an elderly Italian man with an acute fulminant HEV infection genotype 3e that developed in the context of pre-existing liver disease; this is the first case of an unfavourable outcome associated with subgenotype 3e. The potential pathogenicity of this subgenotype together with the influence of host-related risk factors are discussed.

RESUMEN

UNLABELLED: BACKGROUND AND RATIONALE OF THE STUDY: Effect of Long-term nucleoside/nucleotide (NUC) on hepatocellular carcinoma (HCC) incidence in a population of HBeAg-negative genotype D patients has not been adequately studied in real-life cohorts. Our aim was to evaluate the impact of liver fibrosis and other variables on HCC incidence in this population of patients. Of 745 patients with chronic hepatitis B (CHB), 306 HBeAg-negative genotype D were selected and included in this study. All patients received treatment with NUC for at least 18 months. Patients with CHB or compensated cirrhosis were included. Patients with HCC diagnosed before or during the first 18 months of NUC therapy were excluded. RESULTS: HCC was diagnosed in 2 CHB patients (1.0%) and 23 cirrhosis patients (20%) (OR = 24.41, 95% CI 5.40 < OR < 153.2; p < 0.0001). Multivariate analysis revealed that HCC risk was independently associated with age ≥ 60 years (OR = 6.45, 95% CI 1.22 to 34.0; p = 0.02) and liver cirrhosis (OR = 12.1, 95% CI 1.39 to 106.2; p = 0.02), but not with virological response (VR), and previous resistance to NUC, or rescue therapy. Multivariate analysis in cirrhosis patients revealed that only age ≥ 60 years was an independent risk factor associated with HCC (p = 0.003). CONCLUSIONS: Liver cirrhosis and age ≥ 60 years are the stronger risk factors for HCC in genotype D HBeA-gnegative patients. Previous resistance to NUC in patients that achieved a VR after rescue therapy was not a predictive factor regarding HCC. VR does not appear to significantly reduce the overall incidence of HCC when a patient has already progressed to liver cirrhosis.

RESUMEN

PURPOSE: The aim of our study was to evaluate the diagnostic accuracy of gadoxetic acid-enhanced magnetic resonance (MR) imaging both in the detection of hepatocellular carcinoma (HCC) and precancerous lesions and in the assessment of their evolution. MATERIALS AND METHODS: A retrospective study was undertaken on 56 patients with chronic liver disease and suspected liver lesions. We evaluated the number, size and signal intensity of the nodules on dynamic and hepatobiliary MR images. Follow-up studies were carried out every 3 months. Statistical analysis was performed using the Fisher's exact test. RESULTS: A total of 120 nodules were identified in 41 patients. Of these, 92/120 nodules (76.6%; mean diameter 18.4 mm) showed the typical HCC vascular pattern: 90/92 nodules appeared hypointense and 2/92 were hyperintense on hepatobiliary phase images. An additional 28/120 hypointense, nonhypervascular nodules (23.3%; mean diameter 11 mm) were detected on hepatobiliary phase images, 15 of which showed hypointensity also on the equilibrium phase images. During the 3- to 12-month follow-up, 14/28 nodules (mean diameter 13.3 mm) developed the typical vascular pattern of HCC. CONCLUSIONS: Gadoxetic acid-enhanced MR imaging is useful for detecting HCC as well as hypovascular nodules with potential progression to HCC. Lesions measuring more than 10 mm in diameter are at higher risk of developing into HCC (p = 0.0128).

RESUMEN

BACKGROUND AND AIMS: Sarcopenia has been associated with poor outcomes in patients with cirrhosis and hepatocellular carcinoma. We investigated the impact of sarcopenia on survival in patients with advanced hepatocellular carcinoma treated with Sorafenib. METHODS: A total of 328 patients were retrospectively analyzed. All patients had an abdominal CT scan within 8 weeks prior to the start of treatment. Two cohorts of patients were analyzed: the "Training Group" (215 patients) and the "Validation Group" (113 patients). Sarcopenia was defined by reduced skeletal muscle index, calculated from an L3 section CT image. RESULTS: Sarcopenia was present in 48% of the training group and 50% of the validation group. At multivariate analysis, sarcopenia (HR: 1.47, p = 0.026 in training; HR 1.99, p = 0.033 in validation) and MELD > 9 (HR: 1.37, p = 0.037 in training; HR 1.78, p = 0.035 in validation) emerged as independent prognostic factors in both groups. We assembled a prognostic indicator named "SARCO-MELD" based on the two independent prognostic factors, creating three groups: group 1 (0 prognostic factors), group 2 (1 factor) and group 3 (2 factors), the latter with significantly worse survival and shorter time receiving treatment.

RESUMEN

OBJECTIVES: Here we investigate Hepatitis D virus (HDV)-prevalence in Italy and its fluctuations over time and we provide an extensive characterization of HDV-infected patients. METHODS: The rate of HDV seroprevalence and HDV chronicity was assessed in 1579 hepatitis B surface antigen (HBsAg)+ patients collected from 2005 to 2022 in Central Italy. RESULTS: In total, 45.3% of HBsAg+ patients received HDV screening with an increasing temporal trend: 15.6% (2005-2010), 45.0% (2011-2014), 49.4% (2015-2018), 71.8% (2019-2022). By multivariable model, factors correlated with the lack of HDV screening were alanine-aminotransferase (ALT) less than two times of upper limit of normality (<2ULN) and previous time windows (P <0.002). Furthermore, 13.4% of HDV-screened patients resulted anti-HDV+ with a stable temporal trend. Among them, 80.8% had detectable HDV-ribonucleic acid (RNA) (median [IQR]:4.6 [3.6-5.6] log copies/ml) with altered ALT in 89.3% (median [IQR]:92 [62-177] U/L). Anti-HDV+ patients from Eastern/South-eastern Europe were younger than Italians (44 [37-54] vs 53 [47-62] years, P <0.0001), less frequently nucleos(t)ide analogs (NUC)-treated (58.5% vs 80%, P = 0.026) with higher HDV-RNA (4.8 [3.6-5.8] vs 3.9 [1.4-4.9] log copies/ml, P = 0.016) and HBsAg (9461 [4159-24,532] vs 4447 [737-13,336] IU/ml, P = 0.032). Phylogenetic analysis revealed the circulation of HDV subgenotype 1e (47.4%) and -1c (52.6%). Notably, subgenotype 1e correlated with higher ALT than 1c (168 [89-190] vs 58 [54-88] U/l, P = 0.015) despite comparable HDV-RNA. CONCLUSIONS: HDV-screening awareness is increasing over time even if some gaps persist to achieve HDV screening in all HBsAg+ patients. HDV prevalence in tertiary care centers tend to scarcely decline in native/non-native patients. Detection of subgenotypes, triggering variable inflammatory stimuli, supports the need to expand HDV molecular characterization.

RESUMEN

AIM: Adherence to and the applicability of practice guidelines for the management of hepatocellular carcinoma (HCC) in field practice have not been fully addressed. We designed a multicenter field practice prospective study to evaluate the adherence to the 2005 American Association for the Study of Liver Diseases guidelines in Italy. MATERIALS & METHODS: The study began in September 2008 and consecutively enrolled cirrhotic patients with newly diagnosed HCC from 30 local, nonreference centers in Italy. Patients were stratified according to Child-Pugh, the model for end-stage liver disease, tumor-node metastasis, performance status and the Barcelona Clinic Liver Cancer (BCLC) classifications. The diagnostic and therapeutic strategies adopted in each individual patient were recorded. Statistical analysis was carried out on 536 patients using all of the valuable data. RESULTS: A total of 286 (54.5%) patients were ≥70 years old. Comorbidities, recorded in 397 (74%) patients, were classified as moderate to severe in 170 patients (43%). Overall, 174 (59%) patients with early-stage BCLC were ≥70 years; 104 (35%) of these had moderate-to-severe comorbidities and 54% were under a regular US surveillance program. Diagnosis was performed by computed tomography in 93% of patients, contrast-enhanced ultrasound in 62% and MRI in 17%. In patients with nodules of ≤2 cm, adherence to noninvasive diagnostic criteria was 56%. Adherence to the BCLC classification was shown to be suboptimal overall, particularly regarding allocation to surgical procedures, and a total of 119 patients (40%) with BCLC stage A did not receive curative therapies. CONCLUSIONS: This multicenter survey showed that, in the 'real world', adherence to the both the diagnostic and therapeutic American Association for the Study of Liver Diseases 2005 algorithms was low, particularly in patients with early-stage HCC. Difficulties in applying the algorithms in routine clinical practice and the high prevalence of older patients with relevant comorbidities may account for our findings. Strategies to help improve adherence to international guidelines for HCC in field practice are required.

RESUMEN

BACKGROUND AND AIMS: Few reports, all retrospective, have evaluated vaccine coverage against COVID-19 infection in cirrhotic subjects. No data are available for European Countries. We aimed to explore this topic and potential independent predictors of lack of vaccination. METHODS: Between January 1st and June 30th 2022, 1512 cirrhotic subjects of any etiology were consecutively enrolled in an observational - prospective study in 8 referral centers in Italy. Adjusted Odds Ratios (O.R.) for the association with lack of vaccination and with occurrence of breakthrough infection were evaluated by multiple logistic regression analysis. RESULTS: Overall vaccine coverage was 89.7% (80% among people born abroad). Among the 1358 vaccinated people, 178 (13.1%) had a breakthrough infection; of them 12 (6.7%) were hospitalized, but none died. Independent predictors associated with lack of vaccination were birth abroad, age <65 years and lower years of schooling. Child stage B/C was the only independent predictor of breakthrough infection. Occurrence of breakthrough infection was more likely reported in subjects who received 2 doses of vaccine than in those who received 3 doses (33.9% versus 9.0%; P<0.001). CONCLUSION: High vaccine coverage against COVID-19 infection is observed among cirrhotic subjects in Italy. Vaccine is effective in preventing severe outcomes. Three doses are more effective than two, even in cirrhotic subjects. LAY SUMMARY: This large cohort study evidenced high vaccine coverage against COVID-19 infection among cirrhotic subjects in a European country and the effectiveness of vaccine in preventing severe outcomes. Three doses of vaccine are more effective than two in preventing breakthrough infection and hospitalization. Informative campaigns targeting people younger than 65 years of age and those with lower years of schooling may increase these excellent results.
